automatic metal sheet pretreatment machine of stee

the “pretreatment machine of steel door manufacturing line” adopt complete program-controlled, quick process to cold-rolled steel sheets (degreasing, roughening, passivation and drying). Space occupied is less than trasitional phosphating equipment. The powder adhesiveness is improved greatly. The follow-up process can be finished mechanically. The quality of surface finish is stable and under control. Running cost is decreased, and no pollutant emissions. External size: LxW=12000x1800mm Work piece size: δ=0.3-2.5mm, W≤1100mm sheet metal; Labor required: 2-3 workers; Capacity: δ=0.7mm LxW=2000x1000mm sheet. 120-200pieces per hour We have developed steel doormanufacturing line advanced technology instead of traditional way, especially the steel door with wood finish and pattern. We offer the vacuum transfer printing machine to do wood finish, and VD washing line to do pretreatment, flexible powder coating line to do painting. If you want to set up your own factory to manufacture steel door, we have full solution of machinery and technology. If you want to buy the steel door leaf in wood effect and pressed patterns, we have various design for you to choose from.
